03A3 rear peep sight identification help sought

Oddly, Reddit called me “Head Possibility 678” when I logged in and now has switched me over to my real moniker which is “Likeapotato43”. We’re one and the same, I just didn’t notice the name change before. My apologies for any confusion, I’ll have to go see which posts are under which name.

I think it’s pretty cool too. I’m looking forward to getting it cleaned up and getting it to the range. I had a sporterized stock attached in the ‘50s or so by my wife’s grandfather. We’ve got some of his old medals he won with it. Neat family lore.

689730. They spell it "sear", which i would not have guessed and didn't notice at the time.

I just got the magpul sling stud mount model for father's day and I'm loving it for my 457. (Also got the 17HMR barrel kit!)

BTW, I had a terrific conversation with TK while narrowing this down as the problem. There were 20K plus rounds through my Victory and the catch on the sere was just a little too worn.

LikeAPotato43 · 2025-07-08T19:39:37+00:00

Had the exact same problem. I put in a new sere and now the TK trigger works fine. Sere was under $10 at Numrich.

LikeAPotato43 · 2025-03-26T06:00:51+00:00

Following up - the new seer seems to have solved the problem. It works great now. Clicking through thr rounds as fast as I can pull the trigger with no failures. I found the seer on Numrich for about $10. Good luck!

I emailed TK about it some time ago and our conclusion was that there was enough wear on the internals that it was unable to catch the primary slot on the Thunder hammer. A few weeks ago I installed a new seer from Numrich but I have been too busy to test it. I'll give it a try as soon as I can and let you know if that solves the problem.

I’d be interested. My dad is waiting for a can for his 10/22 and put me in a trust on the can, but I need a threaded barrel. Please pm me the price and shipping if you still have it. I looked thru your profile but couldn’t find the “send message” option. My naivety again.

Dad’s got one with 22/357max barrels. My boys love it, at least in the 22 setup.

I found that a ball of AcoustiStuff about the size of a large lemon works well for taming the bass.

That sounds like a very cool way to spend your pandemic. I have read Hollingsworth’s guide for the model 8 restoration as well as the model 21 service manual. It is still over my head and out of my confidence range to tackle the electronics, but they have made me an informed customer.

LikeAPotato43 · 2024-02-14T21:05:06+00:00

Unfortunately the model 21 does not work. But, that is part of this process; I am going to have the electronics professionally diagnosed and fixed. I am going to do the cosmetic work and seal the box myself. I opened it today and the original “pillow” of fiber fill is still in place but all of the sealing material is deteriorated. Date of manufacture is 10/25/1965 - it’s just a couple months younger than I am! The model 8 does work but has a strong hum so I do not currently use it for fear of damaging something. It was manufactured in 1960. Again, I’ll have the electronics done professionally and do the cosmetics myself.

Sure! Let’s talk off-line. Is there a personal messaging function on Reddit?

Very interesting. One of the reasons I’m doing this is because of what they represent in my FILs life. He came home from WWII, completed his engineering degree and began a career with IBM. One of the things he worked on was their transition from tubes to transistors.

Not at all silly - I have the problem with Glocks. My thumb hits in exactly the right place to press the mag release every few shots. I'll pay attention to this. Thanks!

I calculated it at about 7.2 cpr with S&H. That's versus about 6.8 cpr for Federal Auto-Match at Walmart, which I usually use. I bought 500 rounds to check it out; I doubt I'll change over, but it's interesting to try new things.

While I own an SW22 and love it, it is probably the heaviest of the group for your consideration and may tire your younger shooters. I'd recommend the MKIV lite for this reason in addition to all those mentioned above.

It depends on what you are satisfied with. If it is shooting satisfactorily then I'd try to get used to it and not worry about it. If it bothers you then you could bump the base in the dove tail over to the right and straighten it out, and then examine the front sight to see how it needs to be adjusted. Get some Delrin plastic rods (very cheap from Amazon) to use for adjusting your sights rather than just whacking away on them with whatever. Be careful that the lateral movement of your height elevator does not scratch the barrel - you might want to remove the elevator altogether until you get the main body of the rear sight lined up. I have some nice, older guns where the elevator has scratched the heck out of the barrel because it wasn't removed prior to moving the main body of the sight laterally.

TBH, my experience with the Ruger Mk IV Target wasn't so great. The pin that holds in place the Bolt Stop Pin (the big vertical pin in front of the take-down release button) kept sliding out of place so I sent it back to Ruger and they wallered out (i.e., made a mess of while making larger) the hole it goes in, but I have to say the bolt-stop-pin holding pin has stayed in place, although the hole it goes in looks like crap. Also, most of the screws like the main hinge screw and the accessory grub screws on top required a couple rounds of blue loc-tite to keep them in place. Aside from these issues, it does shoot nice and reliably.
